If you prioritize a wireless experience and features like active noise cancelling, sweatproof certification, and longer battery life (7.5 hours against 6.4, plus the case battery), the Sennheiser Momentum True Wireless 4 would be better for you. However, it's at a premium price point and may not be as suitable if you're looking for a wired connection or a lighter option for portability. The Etymotic ER4XR, while cheaper, offers excellent sound isolation and build quality but lacks wireless functionality and modern features such as app equalization or touch controls. It's also not the best for exercise or travel due to its poor scores in those areas. If you're after immersive sound for music without much concern for gaming or TV latency, the Sennheiser would be a smart choice. But if you want to save money and prefer the reliability of a wired connection with high sound quality, the Etymotic could serve you well, especially for focused listening situations. Give Feedback

What HiFi? | May 2015
"The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening. While the soundstage is large rather than gigantic, the excellent separation and spatial precision mean you can dive deep into music just as much as when wearing a pair of full-size open-backed headphones."

"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
